DOOR CHECK R STOP.

Application filed August 4., 1927. Serial No. 210,489.,

r I This invention relates generally to door I casing and door withoutimpairing the strength of either and a still further object is toprovide a device in which the tension of the arresting spring can beadjusted as desired. A still further object is to provide a devicewhichshall be exceedingly simple and inexpensive.

With these various objects in view the invention consists in the novelfeatures of construction and in the manner of combining or arran ing thesame all of which will be fully descri ed hereinafter and set forth inthe appended claims.

In the drawings forming a part of this specification I have shown oneform of my invention and in which Fig. 1 is a perspective view showingparts of the door and easing,

frames with my invention applied thereto; Fig. 2 is a horizontalsectional View showing certain parts in plan; Fig. 3 is a detailsectional View showing the manner of connecting the rod to the loopedplate carried by the easing and Fig. 4: is a face view of the retainingwasher.

Referring to the drawings, 10 indicates a casing member of theautomobile and 11 a member ofthe door frame, said parts being connectedtogether by means of the usual type of hinge 12. The face of the casingmember 10 is recessed as shown at 13 and in,

this recess is fitted the looped plate 14, the outer vertical membersbeing secured to the face of the casing while the parallel portionsthereof fit into the recess, as most clearly shown in Fig. 3.

Pivotally connected to the looped plate by means of a pivot 15 is oneend of a flat rod 16, said rod passing through a kerf 17 cut in the doorframe 11, the free end of said flat rod having oppositely disposednotches 18 cut in opposite sides thereof. The kerf 17 is made flaring,as shown, in order to accommodate the swinging movement of the flat rodas the door is swung upon the hinge 12. The opposite face of the doorframe is cut away as indicated at 19 and seated in said cut-away portionis a cushioning strip 20 of leather or other suitable material andthrough which the flat rod 16 passes.

A coil spring 21 surrounds the free end of the flat rod 16, one end ofsaid spring contacting with the cushioning strip 20 while the other endcontacts with a flanged disk 22 which is slotted to receive the end ofthe rod. This flanged disk 22 receives a washer 23 which in turn isprovided with a wide slot oropening 2 1 for engagement with the notchedend of the rod 16, it being possible to adjust. this washer along therod 16 and engage it in any one of the series of notches 18 in order toimpart the desired tension to the spring 21, or to change the limit towhich the door may be opened and thereby permit a door check of a untilthe flanged disk ment will be arrested by the rod 16 carrying at itsfree end the stop washer which in turn bears upon the coiled springwhich is compressed as the door .is swung to a position substantially atright angles to its normal or closedposition. The kerfs andrecess'esbeing thin or narrow do not impair the strength of the membersin which they are made.

' All of the metal parts of the door check with the exception of thecoil spring 21 are formed by stamping the same fromsheet 0 metal thusmaking possible the production of the door check at a minimum cost.

With the parts of the bracket arranged as above described andillustrated, the maximum strength is obtained from the material used..By using a flat bar 16 and pivoting it to swing in the plane of the barthe Width of the material resists any tendency of the door to bend thebar as the door reaches the limit of its swing.

By using the particular adjustable stop assembly or its equivalent,threading of the rod 16 is obviated and the rod may be formed by asingle operation, and with the flat bar pivoted between ears ofsubstantial width on the bracket 14 the parts remain tight for a longperiod of time and rattling of the parts when in use is eliminated.

Having thus described my invention, what I claim is:

1. In combination withelements comprisinga door and easing, a check forsaid door comprising a sheet metal bracket member secured to one of saidelements and having an ear portion, a flat rigid bar pivoted at one endto said ear to swing inthe plane of the width of said bar, the other ofsaid elements having a slot through which said bar projects, the freeend of said bar having spaced recesses therein, an adjustable stophaving means for engagingin said recesses to retain the same in anydesired position of adjustment on said bar, and a resilient element onsaid bar disposed between the inner face of the slotted element and saidstop.

2.- In combination with elements comprising a door and casing, a checkfor said door comprising a sheet metal bracket member secured to one ofsaid elements and havingan sitely disposed notches, a bifurcated memberadapted to engage in any pair of said notches,

a cup washer member received on said bar and in which said bifurcatedmember fits for re-. taining it in placeyand a resilient member on saidbar and interposed between said cup washer and the inner side of saidslotted element.

In testimony whereof, I hereunto afiix my signature.

ALBERT C. EARHART.
